FIELD: industrial organic synthesis.
SUBSTANCE: linear alpha-methylstyrene dimers that can be used as molecular weight regulators for various polymers, as varnish solvents, and as base material in production of synthetic oils are obtained via oligomerization of α-methylstyrene in presence of zeolite ZSM-12 in H form in amount 1 to 10% at temperature 60-120°C.
EFFECT: increased selectivity and simplified production process.
